Verfahren und Vorrichtung zum Vorwalzen von Brammen bezueglich ihrer Breite

摘要

When roughing a continuously cast slab in a continuous hot rolling stand, the invention breaks down the width of the slab, having passed through a vertical scale breaker, by means of rolls having at least a pair of pressing calibers and thereafter the width of the slab is rolled by means of vertical rolls whereby the width of the slab is rolled more accurately than was possible in the prior art, and accordingly changes of molds of continuous casting machines are no longer required during the continuous casting operation and such an operation is possible over many charges.
